The stochastic dominance ordering over probability distributions is one of the most familiar concepts in economic and financial analysis. One difficulty with stochastic dominance is that many distributions are not ranked at all, even when arbitrarily close to other distributions that are....

This paper constructs a robust optimization framework of the uncertain worst-case return. The model defines an adjustable discrete uncertainty set which controls the conservatism of the optimal asset allocation. Without prior assumptions on the data generating process, the model also develops an...

We study a dynamic and infinite{dimensional model with incomplete multiple prior preferences. In interior efficient allocations, agents share a common risk{adjusted prior and subjective interest rate. Interior efficient allocations and equilibria coincide with those of economies with subjective...

We propose a model of decision making that captures reluctance to bet when the decision maker (DM) perceives that she lacks adequate in- formation or expertise about the underlying contingencies.

We consider a model with an finite number of states of nature where short sells are allowed.

In this paper we deal with the basic two-period consumption saving problem where the first and second period consumption utility, v and u is assumed to be concave re- spectively as usually. We prove that for the rank dependent utility model, prudence is fully characterized by the convexity of u/...

In this paper, we examine the eect of a decrease in risk on the demand for risky asset in the standard portfolio problem. We introduce a new class of dominance, that we name relative order and we prove that this class of dominance is consistent both with central dominance introduced by Gollier...

We consider a model with an inffnite number of states of nature, von Neumann - Morgenstern utilities, where agents have different probabil- ity beliefs and where short sells are allowed. We show that no-arbitrage conditions, deffned for ffnite dimensional asset markets models, are not sufficient...

This paper proposes to investigate the impact of ?nancialization on energy markets (oil, gas, coal, and electricity European forward prices) during both normal times and periods of extreme ?uctuation through an original behavioral and emotional approach. With this aim, we propose a new...

This article reconsiders the theory of existence of efficient allocations and equilibria when consumption sets are unbounded below under the assumption that agents have incomplete preferences. It is motivated by an example in the theory of assets with short-selling where there is risk and...
